Chelsea boss Frank Lampard says it's too soon to discuss his playing philosophy.

Lampard, ahead of today's clash at Manchester United, says a style of play remains a moving target.

"Last season was very positive for us because we had an identity as a team that worked very hard off the ball, created a lot of chances, tried to get higher up the pitch and made a lot of steps forward, while also knowing we needed to go further," he explained.

"We have new players that have come in this season and there has been a period where we've had to work again so I don't want to sit here and commit to what my philosophy will be in a year or two years because the reality of football is that it moves on a lot.

"In real time, you have to work with the players you have and keep trying to improve."
